yThis invention relates to 'improvements in gasjburne'rs, and the objects 'of the'invention are to provide a simply constructed fand economical device ofthis'lzind sov con-v Y 5 structed thatthe several parts will'more etfficiently: performihe variousV functions renovel larrangement and construction of; parts as described in the,presentspecifica-.

tion'and illustrated by the accompanying drawings that Jforinpart'of the sa`n'f'ie.`y

Referriiignow to the drawings in which likeA characters Vof reference indicate corresponding parts in each iigurei i jbodiment of my device.' u Y `Figure 2 is a longitudinal section. y

Figure 3 is a section on line 3-43 of F1gment of myfdevice as afwhole,A the essential features of whichwarefa box; or casingV 10 provided witha .suitable opening-11 with burner ring 12. Into the yopening 11 isA designed to'fit ay conical-shaped spreader 13 adapted tobe raised or lowered to allow the niixture of air from either oneA or both sup-4 `ply pipes to spread flame having integral j 'therewith a stem portion' 14' and suitable supportingv means thereon 15. The box 10 f is Vdivided substantially midway of itslength vby a suitablepartition 16y designed to reg-i c isterwiththe opening 119so that th-ebox is jevenlyj divided' into ltwocompartments to `ei'iable only'j onejsupply to be used as vrei 17 and 18amr aas SUP-Ply pipes cmmu'i- ,v eating with thebox 10 as illustrated, both.

'and Vdesigned to regulate the admission'fof Figure 1 Vis a perspective view of an em'- l Y trolled. In the drawings A designates an embodi-V tli'ese pipes being providedl with mixingY chambers 19 land 20 into which the gas is p delivered by the restricted pipes 21 vand 22. i Y i The pipes 17 and'lSare also provided with sleeves 23 and 2tslidably` mountedV thereon the additional air lto the burner.

To regulate the spreadery 18 I provide a cani-shaped member 25,1pivotally1 mounted Within the box 10 and designed to contact with the stem 14. The .cam-shaped member Y is formedwithV an vintegral. arm 2 6 e'xtenda` 55 ing beneath the box and pivotally connected at 2T to an operating rod 28 suitablyjsup'- ported by a bracket29 on one ofthe mixingchambers and whereby,l on the rod y'beii'ig 4moved inwardly,fthe stem 14 of thespreadery '60 isallowedto-,dro into the aperturell, and 1 wherebyfon the rod being ldrawn forward',-` the stem is shoved upwardly thereby opening theaperturerll in thetop of the' box.

From the foregoing it` willbe seen 4that ,65 the flow ofl the mixture. of' gas land air through the supply pipes 17 and 18 .to `the` j burner can besimplyand,adequately con# -As many? changes could be made inthe 7i) above construction and many apparentlyk widely 'diierent embodiments of 'my invene tion, within the scope ofthe claim, conj v structed without. departing from thescope or spirit thereof,V it isintended that allmat- 75 ter contained in the accompanying specifi# cation and drawings shalll be interpreted'l in an illustrative and notin a liiniting sense.

What' I claimas my inventionis:

A burner` box: having a circular openings() c. f y in the top, a `vertical partitioninthe box; ,Y substantially midwayfthereof and contacting-the top at they opening, a flamefspreader providedv with-a stem Vmounted yslidably on the partition andada-pte'dfto 'iit'intoy the'an-S5 i" nular.` opening,V and means for raisingjandA Ylowering said stem. f n.
